偏心套的机械加工工艺规程及工艺装备设计.doc

辽宁工程技术大学课程设计题目:偏心套的机械加工工艺规程及工艺装备设计班级: 姓名: 指导教师: 完成日期: 摘要现今的世界国家间的竞争已经全面转入科学技术的竞争, 而机械工业直接反应一个。无论是核工业还是农具,机械制造业是国家获取其他几乎一切行业设施和工具的来源。可以说人类文明史就是机械制造的历史。我国的工业化建设情况, 国际上众说纷纭, 虽然在很多高技术项目上颇有建树,但在这次汶川地震中表现出中众多缺陷。包括规模较小,工艺粗糙,关键技术仍依赖国外等等。充分说明在向高技术领域进军的同时,低端产业也应该加强建设。本说明书是为加工机械零件偏心套的加工过程而编写。偏心套以其偏心结构实现内孔直径可调, 加上紧定螺丝,以达到内圈周向、轴向固定的目的。但因为内圈内孔是间隙配合, 一般只用于轻载、无冲击的场合。是一种较为常见的机械零件。关键词:偏心套零件加工过程 ABSTRACT Nowadays ,petition ofworld countr ies has shift petition ofnew science and pletely,In this age ,level ofdevelopment for the machine industry has e the most important criteria inthe judgement inacountr y’slevel ofdevelopment .From Nuclear industry todead stoc k,ALL the establishment and facilities ,hat our country need and consume ,depend onour machine industry .The histroy ofmankind isthe histroy ofthe machine building Consider chinese industry construction ,Many argumentation shas been bring forward inthe anization .We enjoy our achievement in some new technolog inthese serious earthquake inWENCHUAN,we discover edour weakness :dimensions ,asperous technics ,core technology depend onother notwithstanding these isthe age ofadvanced krowlage,we must improve our well-rounded technolog ies.
